Mountain Lion is Out

I like everything in a complete package. Personal preference. This is my first OS upgrade. I bought my first mac earlier in the year. Last time I touched a mac was in the '80s. I have a lot of catching up to do and learning how the mac works. I've always used windows since 3.1.

Question about having the GM version installed... do you also have to buy the released version so that the Mac App Store recognizes your copy and can/will update it? Since the GM version wasn't released through the MAS, how does it know to do the updates when software patches are released?

From what I heard, as long as your on the GM it will recognize updates. We'll find out for sure when the first update comes.

One of the alleged Mountain Lion features is: "You only need to log into facebook once... and then all your facebook contacts synch w/ your Contacts." Sadly, this hasn't happened... how do I get it to work?

It spelled out pretty clearly upon release that the Facebook support and features were coming this fall...

I haven't really noticed. My MacBook usually gets a couple of hours of usage before I have to plug it in and it appears to be the same now that I have Mountain Lion installed, but I'll try to gauge the battery life the next time I'm using it.

I haven't done any scientific comparisons but the battery life seems about the same on my MBA after the upgrade. It does appear that some users are experiencing worse battery life after the upgrade though based on some articles I have read. Here's one:
